I need expert knowledge.

I bought a 1970 chevy pickup and i am new to these trucks. I want the 67-68 hood but I have been told that i will also have to change the fenders and radiator support if i want to do this. I guess my question is if this is true or not. I have planned to shave my existing fender's marker lights but if I find that i will have to get fenders along with a hood i will just go ahead and get a 67 dog house. To save me some work. And is there a place where i can get a floor pan with a high hump like in a 4WD? I've looked everywhere and all i can find avalible are 2WD floor pans. I guess I can order the hump seperate and install it but I'd rather have it clean frome the press.
